Обсуждение: Are there programs to graph database schema?
I know that there are standard ways to graph relational databases. It occured to me that perhaps programs existed which simply parsed the table definitions and plotted the graphs for you. Anyone know of such a thing? Thanks. -Tony

Hi, I use MS Visio Professional, and it works (not very good), but it works. I ever wondered if there is a opensource tool, that let me create an automatic ER-Model diagram from an existing DB, like MS Visio. Do you know if this tool exists ?

Hi, For a small schema, i've used PGACESS. There is a graphical editor which help you to draw boxes with the foreign keys.

Guten Tag Juan Miguel, Hi Juan, JM> Hi, I use MS Visio Professional, and it works (not very good), but it works.

Unfortunately I don't. I am unsatisfied with Visio too, but the point of reason for using it is exactly that I don't know a better tool. If anybody does - please let me know! Rico

Hi All , Have a look at DbVisualizer-4.0.2 Java based ER tool that works very well. Regards. Leslie.

We recently purchased DBVisualizer. It's really quite good for this kind of diagram (some quirks). http://www.dbvis.com It's not open source though and you do have a small charge to pay.

hello tony, Our tool DeZign for Databases can do this for you. With the ImportER Scripts add-on you can import SQL scripts containing create table statements etc into the data modeling tool DeZign for Databases. more info at http://www.datanamic.com regards rick reina_ga@hotmail.com (Tony Reina) wrote in message news:<272e4be7.0401121419.37989e3a@posting.google.com>... > I know that there are standard ways to graph relational databases. > > It occured to me that perhaps programs existed which simply parsed the > table definitions and plotted the graphs for you. > > Anyone know of such a thing? > > Thanks. > -Tony
